To address this, we propose an Unbiased Label Distribution (ULD) to eliminate quantization error in training targets.

The core idea is to take the geometric connection between the classes into the label coding process. The first one is named static soft label coding (SSLC), which modifies the one-hot codes into soft codes based on the distances between the local areas.
